Teollisuuden Voima OyjCompany

Teollisuuden Voima Oyj is a non-listed public company founded in 1969 to produce electricity for its shareholders at cost price. TVO’s nuclear power plant produces about one sixth of the electricity consumed in Finland. Electricity is generated at the two Olkiluoto nuclear power plant units Olkiluoto 1 and Olkiluoto 2 (OL1 and OL2) in Eurajoki and at the Meri-Pori coal-fired power plant in Pori. A new unit, Olkiluoto 3 (OL3), is under construction in Olkiluoto. In July 2010 the Finnish Parliament ratified the Government’s favourable decision-in-principle on the Company’s application for the construction of its fourth nuclear power plant unit Olkiluoto 4 (OL4). The planning of OL4 progressed in 2010 to the preparation stage.

We support sustainable wellbeing of the society by producing electricity to Finnish people through a safe, economical and environmentally benign process. Our vision is to be an acknowl-edged Finnish nuclear power company, a pioneer in its field. Our operation is based on our vision, ethical principles and values, and on the safety culture that we maintain. Our safety culture consists of practices, procedures and attitudes. The promotion of safety culture is one of our most important tasks.

The Olkiluoto nuclear power plant produced ca. 14.1 TWh of electricity in 2010. This was about one sixth of all electricity consumed in Finland. TVO’s share of the electricity produced at the Meri-Pori coal-fired plant was ca. 1.6 TWh. The production of the wind power plant totalled 0.001 TWh.

The net output of OL1 was 880 MW. The net output of OL2 is expected to increase from 860 MW to ca. 880 MW after the maintenance outage to be implemented in the spring 2011. TVO’s share of the electricity produced at the Meri-Pori coal-fired power plant is 45%.

Total electricity consumption 2010

The total electricity consumption was 87.5 TWh in Finland in 2010. Industry accounts for 45% of electricity consumption in Finland. Electricity is needed, for example, for driving processes and equipment, lighting, heating and communication. Households use electricity mainly for refrigeration appliances and heating.

As with renewable energy sources such as hydropower, wood and wind, nuclear power provides a way to produce electricity with no carbon dioxide emissions to boost the greenhouse effect. Nuclear power is a very competitive alternative for producing new electricity capacity.
